The `series` function no longer requires an explicit schema. The element
type is now inferred at compile time from subsequent `push` calls using
Hindley-Milner type inference. This simplifies series creation and
aligns with the project's goal of making the untyped AST simple while
the system handles complexity.
Refine the BNF for `series` to explicitly include the `lookback_limit`
and `schema`.
Introduce scope management within the `bind` function for `if/else`
branches to ensure correct context handling during compilation.
Add `Again` and `GetField` node kinds to the `Specializer`.
Improve lexer to ignore invisible characters within identifiers,
demonstrated by a new test case.
Introduces a new AST emitter module responsible for serializing AST
nodes back into Myc source code. This emitter preserves leading comments
and whitespace, enabling a round-trip guarantee for the parser and
emitter.
The documentation in `docs/BNF.md` has been updated to reflect the new
syntax rules for comments, including single-line comments (`;`) and
documentation comments (`;;`). The rules clarify that comments must be
whole lines and that inline comments are disallowed.
The lexer and AST node structures have been updated to accommodate
`CommentLine` variants, allowing for different types of comments
(regular, documentation, and blank lines) to be stored and processed.
A new test suite `tests/comment_roundtrip.rs` has been added to verify
the round-trip property of the parser and emitter across all example
`.myc` files. This test ensures that parsing source code, emitting it,
and then parsing the emitted code again results in the same output
string.
The `ast.rs` binary now includes a `--emit` flag that uses the new
emitter to output the parsed source code, facilitating debugging and
testing of the emitter itself.
Integrates the MCP server functionality into the AST tool binary. This
allows the tool to act as a server for LLM integration, enabling
communication over stdio. The server can list available bindings and
execute scripts.
This commit introduces the BNF for the Myc language, along with its core
semantics, data types, and evaluation logic. It also details the macro
system and provides an overview of the standard library. This document
serves as a foundational context for LLMs to understand and generate Myc
code.
